Question

20 percent of 10 = 10 × ______​

Answer 1

Percentage solution with steps:

Step 1: Our output value is 10.

Step 2: We represent the unknown value with X

Step 3: From step 1 above, 10 = 100%

Step 4: Similarly, X = 20%

Step 5: This results in a pair of simple equations:

10 = 100% (1)

X = 20%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

10 100% 20%

X

Step 7: Again, the reciprocal of both sides gives

⇒x=2

Therefore, 20% of 10 is 2
